Abstract
The distributions and diversity of Odonata (dragonflies and damselflies) in Arizona have been rapidly changing (Figure 1). Most of the species that were present in the state 60 years ago are still resident. But many other species of these aquatic flying insects are newcomers to Arizona, flying in to exploit available niches and in doing so establishing new populations. In writing this paper, we are calling attention to seven species of odonata that seem to have become Arizona residents, to one degree or another. We are attempting to document their changes in distribution during the years 2008 through 2018. Those 10 years appear to be a decade of great biological flux in the American Southwest and it will be interesting to use the decade as a baseline for other 10-year periods and their resulting distributional changes. While other species have made inroads into Arizona's biota, perhaps to a lesser degree, these seven stand out for reasons as discussed below.
